The LG B2 OLED TV is generally better for dark room viewing due to its infinite contrast ratio and perfect black levels, which enhance movie watching and gaming. It does not get as bright, which can be a drawback in very well-lit rooms. The Sony X90L LCD TV, on the other hand, is brighter, making it more suitable for well-lit rooms. However, its contrast isn't as high as the LG's, affecting its ability to display deep blacks in dark scenes. Both TVs have similar features and smart platform capabilities, but if deep blacks and contrast are crucial for your viewing experience, the LG B2 could be preferred, while the Sony X90L could be more appropriate for bright room usage.

The LG B2 (OLED) is excellent for movies & TV, while the Sony X90L (LCD) is good.
The LG B2 OLED excels in movies & cinematic TV largely due to its perfect black levels, inherent to its OLED technology, providing exceptional contrast, black uniformity, and local dimming capabilities. While the Sony X90L LCD has commendable performance, its slightly inferior local dimming and black uniformity, resulting from its LED backlighting, mean it doesn't deliver the same depth of blacks and contrast that enhance the cinematic experience.

The LG B2 (OLED) is very good for sports, while the Sony X90L (LCD) is good.
The LG B2 OLED TV has an excellent response time and wide viewing angles, making fast-paced sports scenes look very smooth, and it remains clear when viewed from different seating positions. In contrast, the Sony X90L LCD TV, while having very good response time, is not as strong in handling reflections and has narrower viewing angles, which could reduce visibility during sports events when watching with a group or in well-lit rooms.

The Sony X90L (LCD) is very good for bright room, while the LG B2 (OLED) is good.
The Sony X90L performs better in bright rooms largely due to its higher brightness in both standard and high dynamic range content, and despite its poor handling of reflections compared to the LG B2, the overall brightness helps mitigate this downside. The LG B2, with its OLED panel, offers excellent reflection handling and good brightness levels, though it might not outshine the Sony X90L's brightness, it provides exceptional contrast and rich colors which can be preferable in mixed or dimly-lit environments.

Tom's guide
Nick Pino | March 2023
"The LG B2 OLED pairs lush, saturated colors and perfect contrast with a 120Hz screen, HDMI 2.1 ports and a great smart TV platform. The LG B2 OLED is an ideal alternative to the LG C2 OLED for folks who want a taste of OLED life without the sticker price that usually comes with it. The LG B2 OLED does a lot right in terms of performance, color saturation is wonderful and contrast is second-to-none. Not only did color saturation and off-axis viewing impress me, harder to quantify specs like motion processing and upscaling really blew me away as well."
